1. The number of beds in ICU is generally 3-5% of the total beds in the hospital, and 8-12 beds are suitable for each ICU management unit; The bed utilization rate should be 65-75%.
2. In terms of geographical location, it is convenient for patients to transport, check and treat, and the following factors should be considered: close to the main service object ward, operating room, imaging discipline, laboratory and blood bank, etc. when the horizontal "close" cannot be realized, the vertical "close" of upstairs and downstairs should be considered
3. The area of each open bed in ICU is 15 ~ 18m2; Each ICU is less equipped with a single ward, with an area of 18-25m2. The establishment of positive pressure and negative pressure isolation wards in each ICU is usually equipped with 1-2 negative pressure isolation wards.
4.

5. The overall layout of ICU should make the medical area, auxiliary room area, sewage treatment area and auxiliary room area for medical staff have relative independence, so as to reduce mutual interference and facilitate infection control.
6. ICU should have good ventilation and lighting conditions. If possible, it should be equipped with air purification system from top to bottom, which can independently control the indoor temperature and humidity. The temperature in the medical area should be maintained at (24 ± 5) ℃. The air conditioning system of each room should be controlled independently. Install enough inductive hand washing facilities and hand disinfection devices, 1 set for each bed in a single room, and 1 set for each 2 beds in an open hospital bed.
7. ICU should have reasonable medical flow direction including personnel flow and logistics, which can be realized through different entrance and exit channels, so as to minimize all kinds of interference and cross infection.
8. The building decoration of ICU ward must follow the general principles of no dust production, no dust accumulation, corrosion resistance, moisture-proof, mildew proof, anti-static, easy to clean and meet the requirements of fire prevention.
9. The design of ICU should meet the requirements of providing convenient observation conditions for medical staff and access to patients as soon as possible when necessary.
10. In addition to the patient's call signal and the alarm sound of monitoring equipment, the sound of telephone ring, printer and other equipment belongs to ICU noise. In the case of not affecting the normal work, these sounds should be reduced to a small level as far as possible. According to the recommendations of the international noise Association, the noise in ICU should not exceed 45 dB (a) in the daytime, 40 dB (a) in the evening and 20 dB (a) at night. Floor coverings, walls and ceilings should be made of high sound-absorbing building materials.
11. ICU should establish perfect communication system, network and clinical information management system, broadcasting system.
